MECHANICAL MOVEMENT.

To aZZ whom it may concern:

Be it known that I, LUTHER C. THOMP- soN, a citizen of the United States, and a resident of the city of Washington, in the District of Columbia, have invented a new and Improved Mechanical Movement for the Transmission of Power, the following of which is a full, clear, and exact description of the invention, that will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings and the figures and letters of reference thereof, that form a part of this specification.

The object of this my invention is to provide an improved mechanical movement in duplex form that will transmit a generated power to the driving shaft.

This my invention relates to a reversible mechanical movement in connection with a driving shaft having a speed wheel and an eccentric rigidly keyed thereto, and an eccentric ring journaled upon the eccentric. an arm extending from the eccentric ring to the reciprocating guide block, and the said arm being journaled with the reciprocating block. The journaled connections forming a part of said block, and extending through the slotted base supports, and having a journaled connection with the operating lever below the base support.

The reciprocating racks being provided with parallel guides. The actions of the racks and pistons are governed by the reversible movements of the cog wheel, that is timed by the eccentric.

Figure 1 is a longitudinal bottom view of the bed plate, showing the timing levers, and their connecting supports, Fig. 2 is a lonigitudinal top plan view, Fig. 3 is a detached ont elevation of the clutch mechanism,

' Fig. 4 is a top elevation of the rack 11 de tached, Fig. 5 is an end elevation of the motor cylinders connected with the bed plate, and showing the incased exhaust ports. Like letters and figures denote like parts wherever they may occur.

The shaft I is journaled in the boxes L and M that forms a part of the bed plate 19, the speed wheel K is rigidly keyed to the shaft I at I, the ratchet case R and the ratchet case Rbeing rigidly keyed to the drive shaft I, the eccentric 26 is rigidly keyed t0 the drive shaft 1, the eccentric ring lever 1, the opposite end of lever 1 Specification of Letters Patent. Patgntgdl Aug, 28 191*? Application filed September 13, 1916. Serial No. 119,949.

8 is provided with an arm 27, the end thereof being connected with the reciproeating guide block X by the journal 8, the guide block X reciprocates in the guide slot 39, the journal W forms a part of the guide block X and is connected with the end of is hinged at 28 with the link N, the link N," is journaled to the plate 19 at 28, the lever 2 is journaled to the bed plate at 3, the opposite end is journaled to the connecting rod 4 at t, the connecting rod 4; is journaled to the rack 11 at 5, and operates in the slotted opening 16, the connecting bar 25 is journaled to the lever 1 at 1, and journaled to the lever 2 at 2. The revolving movements of shaft I and the eccentric 26 operates the levers 1 and 2 and the rack 11, the cogs in the sides thereof interlocking with the cogwheel 15 that forms a part of the timing mechanism. The reciprocating rack 12 is provided with cogs C at the side thereof that interlock with the cogs of the reversible timing gear 15- The timing gear 15 is journaled in position to the bed plate 19 by the shaft 17, and supported by the bracket 18. The rack 11 is provided with cogs D that interlock with the drive wheel S. The reciprocating rack 12 is provided with cogs D that interlock with the cogs of the drive are insertedin the ratchet case It. The

driving gear S being loosely journaled on the shaft I and having a reversed motion in union with the reciprocating movements of the rack 11. The drive wheel T is loosely journaled upon the shaft I, and is connected to the shaft I by a one-way ratchet clutch R, similar to the ratchet clutch R. The rack 11 and rack 12 are retained in the parallel position with the cylinders 6 and cylinders 6 by the guide plates 14, 14 and 13. The cylinder pistons A and A are rigidly bolted to the racks 11 and 12 at B B, see Fig. 4. The application of power in the cylinder 6 or 6 may be generated by explosive vapor or steam as preferred. The valves are incased in the chambers H H, that form a part of the cylinder heads, but may be constructed in various ways without departing from the spirit of my invention. An explosion of vapor in the cylinders 6 affords a forward movement of the pistons A and the rack 11, revolving the power wheel S, and locking the clutch pawls 21 in the ratchet connections that form a part of the case B. An explosion of vapor in the cylinders 6 forces the pistons A and the rack 12 in a forward movement that interlock the clutch mechanism in the case R, and transmitting the power to the shaft 1, and revolving the timing gear and re ciprocating the rack 11 that is released by the pawls 21, 21. The rotary impulse given to the speed wheel K is not subjected to back pressure on the pistons A and A.

Power is imparted to the rack bars by the pistons which are operated alternately, thus driving shaft I through the gears and ratchet clutches, the ratchet clutches overrunning on the return stroke. The cog wheel 15 serves the purpose of returning the rack bars and pistons after each downward stroke as is plainly evident from the drawi ing. The eccentric in cooperation with the levers 1 and 3 and links connected thereto limits the movement of the rack bars.

Having thus described my invention, what I claim as new in a mechanical movement for the transmission of motor power. and desire to secure by Letters Patent is:

1. In a device of the class described, a plurality of driving reciprocating members, a driven shaft, mechanism connecting said reciprocating members and said driven shaft, for operating said shaft, an eccentric mounted on said shaft, a plurality of connected and pivotally mounted levers, one of said levers being connected to said eccentric, the other of said levers being connected to one of said-reciprocating members, and a gear in operative engagement with both of said reciprocating members.

2. In a device of the class described, a

plurality of reciprocating driving members a driven shaft, mechanism connecting said driving members and said shaft for operating the latter, mechanism connecting said driven shaft and one of said driving mem bers for limiting the throw of said driving members, and a gear in operative engagement with said driving members, for the purpose described and set forth.
